Answer 1

lets say that volume of NaOH is 13,5 ml with concentration of 0,12 M first write neutralization equation to see in what ratios they react then use
c=n/V -> n = c*V to get moles of NaOH and from equation ratio you see how many moles of HCl you have and use that same equation
c= n/V

Answer 2

you need to practice this kind of tasks so they become routine and so you can solve more difficult tasks...

Answer 3

the only thing throwing me off is determine the ml for end point of titration

Answer 4

n im not sure why i keep getting the wrong answer

Answer 5

it is meniscus of solution in buirete

Answer 6

oh so i should add what ever the flask level at plus ten to get my end point tritration in ml?

Answer 7

so 23 mL

Answer 8

no you need to input there a volume you read from buirete

Answer 9

13ml? because if so it telling me im wrong

Answer 10

are you controling the release of NaOH?

Answer 11

if u mean by pour the water with naoh then yes

Answer 12

then you missed the endpoint of titration... do it again...

Answer 13

dont i pour till is turns pink? n tht what i kept getting 13ml.

Answer 14

yes you pour till it turns pink but can you release it slower, that is most common cause of error, too fast release

Answer 15

okay i try it again..

Answer 16

got 13 again.. i stop as soon as it turn full pink from a drop of the water.

Answer 17

you need to stop at first colour change not at full colour...
